Handwriting-Based Model for Identification of Developmental Disorders among North Indian Children
Dhall, Jasmine Kaur
School Psychology International, v37 n1 p51-63 Feb 2016
Handwriting execution is based on the cognitive, kinesthetic, motor skills, and manual co-ordination skills of an individual. The deterioration in handwriting quality is a common implication of neurological disorders. Difficulty and degradation in handwriting has been attributed to the sensory motor deficits prevalent in developmental disorders. In spite of the association between developmental disorders and handwriting ability, the diagnostic potential of handwriting characteristics remains untapped. The present case control study was conducted among 300 subjects aged 6- to 11-years-old of North Indian origin to measure the potentials of handwriting characteristics to identify the selected developmental disorders namely ADHD, AD/HD, CD and DCD. A significant difference was obtained in the kinematics, relative size, number of handwriting defects, spatial orientation, line quality, and the mirror image presence between children with developmental disorders and typically developing (TD) children. A logistic model based on selected handwriting characteristics showed a cross validated 94.9% accuracy rate for diagnosis of developmental disorders. Receiver operator characteristic curve (ROC) analysis was conducted to assess the diagnostic potential of the model as presented by the area under curve was found to be 98.5%. The method is non-invasive, operationally easy and useful for an early identification of developmental disorders by parents and educators.
